Apparently, the CMA Music Festival is A-OK with Luke Bryan and Kimberly Perry, who do their best Fonzies outside a press conference on Saturday. The two will cohost ABC's CMA Musical Festival: Country's Night to Rock on Sept. 17. "We have so much fun playing at CMA Music Festival," Bryan said. “The entire town of Nashville turns into one big party."
